Chara-Branched Algae

Chara (pronounced CARE-ah) is an advanced form of algae often mistaken for higher vascular plants. Common names include muskgrass or stonewort. Identified by a strong musky odor when crushed and a gritty feeling texture due to calcium deposits on the surface. When removed from water Chara will dry out within just a few hours of sunlight exposure appearing ashen to white once dry. Chara will not grow to the surface. Dense growths, attached but not rooted may cover entire bottom of shoreline areas or ponds.

Chara-Branched Algae
Q. What are the best control options?
A.

Algaecide Application:
Cutrine Plus Granular is our #1 recommendation. The active ingredient release of the granule at the bottom near the greatest algae mass is a big plus. Cutrine Plus liquid is also effective especially if algae mass is also near the surface. Copper sulfate is also effective but because it ships HazMat the additional shipping fees for small orders can be prohibitive. Larger orders of approximately 8 plus bags (400 lbs.) can be shipped economically.

Raking:
Raking large areas is too labor intensive. Chara is extremely heavy. Small areas can be hand raked.

Q. When is the best time to treat?
A.

Cutrine granular is best applied early in the growth cycle when lower density growths occur and early in the day if possible. For ponds - do not treat more than 1/3 to 1/2 at a time to prevent oxygen depletion that fish need. See label.

Q. How do I actually apply the product(s)?
A.

The Cutrine Plus granules can be spread by a small hand-held spreader or can be tossed by a hand scoop. A hand held pump up sprayer or Solo backpack sprayer can apply liquids such as Cutrine Plus liquid.

Q. How often do I need to treat Chara (Branched algae)?
A.If you catch it early one treatment can last the season. Two or more treatments may be required when Chara is mature.
Q. How long before I see results?
A.Generally within six to fifteen days depending upon water hardness and growth cycle. things will be cleared up.
